SSL ResourceWarning thrown during normal operation

[0xMochan]

Describe the bug
Normally use Subgrounds via async or sync interface (using query grouping or not) and observe ResourceWarnings.

Expected behavior
No ResourceWarning.

Screenshots

sys:1: ResourceWarning: unclosed <ssl.SSLSocket fd=1588, family=23, type=1, proto=0, laddr=('local_address'), raddr=('remote_address')>

Additional context
This pesky problem was introduced during the async aubgrounds update. It can be safely ignored and even filterd out via the warnings module but ideally we don't have this lingering around.

import warnings                                                           
                                                                              
warnings.filterwarnings('ignore', category=ResourceWarning)

(Fixes #52)

1. Figure out it's correlation between sync and async mode

• I have a feeling it's because query grouping is great for async but a bit weird for sync when using the httpx library.

2. Fix it for each mode
